Caros,
talvez alguem tenha uma dica para resolver um problema com RTLINUX:
Qualquer sugestao é bem-vinda!!
abracos,
alexandre


We recently, have a WR RTLinuxPro v2.2 Subscription and WR LNet Real Time
Networking for RTLinuxPro v2.2.
We have installed the RTLinuxPro successfully and we have check it with the
regression scripts, but we have problems setting up the LNet.
We have one of the recommended Network Card: INTEL PRO/1000 82541GI.
We can make the './lnet/bin/inslnet' and it works, then we can do ./lnetinfo
and we can see the next information.

jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/bin # ./inslnet

===============================================================================

LNet ready!  Below are the locations of some useful utilities.

  '/opt/rtldk-2.2/rtlinuxpro/lnet/bin/lnetinfo'       : display LNet device
info
  '/opt/rtldk-2.2/rtlinuxpro/lnet/bin/lnetmsglvl.rtl' : change LNet
debug-message level
  '/opt/rtldk-2.2/rtlinuxpro/lnet/bin/eth_dump.rtl'   : display received
Ethernet packets

jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/bin # ./lnetinfo
LNet Ethernet dev 0
  Intel Pro/1000 82541GI_LF
  IRQ:22  IO:0xc800  GUID:00:0e:0c:dd:15:92
  IOMEM:0xcdee0000


After that, we configure the IP address of the Lnet device, as you can see
below.

jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/bin # ./lnet_ipconfig.rtl idx=0
mac=00:0e:0c:dd:15:92 ip=138.100.76.211
IPv4 table entry 0 changed:
  [was] mac=00:02:b3:2a:f6:b1 ip=10.0.53.1
  [now] mac=00:0e:0c:dd:15:92 ip=138.100.76.211

Then we think that we can do a ping, to check that the Ethernet works
properly, but when we do that, we get the next error:

 jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/bin # ./ping.rtl target=
138.100.76.1

dev0: PING (138.100.76.1)
ERROR: dev0 rtl_sendmsg() returned -301



The error information on the documentation says: 'Destination IP4 Address
not found in table'. But we don't know how to solve this problem.

We have also try to execute the './ethernet_regression' and we get the next
unsatisfactory message

jordiRTLinux:/opt/rtldk-2.2/rtlinuxpro/lnet/regression # ./regression.sh

Whatever more information that you need I will provide you immediately.



It seems that the problem is on how to link the new module installed 'lnet'
with and Ethernet interface (eth0) o another similar methods that allows to
configure properly the Ethernet (Gateway, etc). I think that when I try to
do a ping the error message sounds like if the system wasn't able to find
the address (gateway problem).



Thanks in advance for you help,
